Describe
Structure and use
 
The valve is composed of a main valve 2, a needle valve 5, a pilot valve 1, a ball valve 3, a pressure gauge 4, and the like. The emergency shut-off valve is used in a water supply system in which fire water and domestic water are connected in parallel in a living quarter. When the fire water is used, the valve automatically shuts down the domestic water to ensure the fire water. When the fire is over, the valve automatically opens to restore domestic water. More cost-effective than traditional fire protection alone.
